Need a good and fast Facebook like button plugin

I want a like button like this http://wordpress.org/extend/plugins/facebook-likes-you/screenshots/. The plugin “Facebook Likes You!” has all I need but it’s really slow on my site and the function exclude post doesn’t work for me. I would also like to have the function to just uncheck it on specific post as the plugin Sharedaddy has instead off typing in the ID.
